When low bearing capacity or excessive building loads add complexity to a project, YGC’s knowledge of various deep foundation solutions will help ensure long-lasting structure performance.
Helical tiebacks are specialized foundation elements typically consisting of square shafts with helical shaped plates installed horizontally into the soil to provide lateral reinforcement and resist tensile forces.
Helical tiebacks are specialized foundation elements consisting of helical-shaped steel shafts installed horizontally into the soil to provide lateral reinforcement and resist tensile forces. Square shaft elements are typically used in these applications considering the loads are in tension only negating any pile buckling potential.
Helical anchors (also referred to as tiebacks) provide lateral stability to foundation walls and retaining walls with unbalanced earth pressures. They offer permanent or temporary slope stabilization, as well as excavation support. Tieback anchors can also be employed as a tie-down application for permanent structures.
Lead sections and shaft extensions are advanced horizontally into the soil provide lateral support when the helical plates are advanced into competent subgrade material. YGC installs helical anchors with hand-held equipment, mini-excavators, skid steers, backhoes, trackhoes, or crane-supported rigs allowing the anchors to be installed in almost any application. This versatility, along with the ability to load and test the anchors immediately, makes this an optimal solution for a variety of projects.
